Biology
There are quite a few. The four most common are: cephalosporins, macrolides, quinolones, and penicillins. However, many of these are cloned and expressed in bacterial hosts.February 9, 2016

Plasma membrane, perhaps. It is semi-permeable not permeable. They are essential for all living cells which includes prokaryotic and eukaryotic organisms. Selectivity due to receptors and other proteins does allow for homeostasis.October 26, 2015

Biology
It would probably be a chloroplast, although they're not only found in plants. Light-dependent reactions take place within these organelles. Although, green is reflected away so it wouldn't be the favorite color, it would be red or blue, depending on the chlorophyll.October 26, 2015

biology
A community simply describes the different population of organisms within a geographic range, it does include any physical characteristics, that's an ecosystem. Think about the organisms you listed and whether you think they could be found together.September 13, 2015
